Case Study: DBATU SGPA & CGPA Grade Calculator
The DBATU SGPA & CGPA Calculator is a specialized web application engineered by SS Code Hub for engineering students enrolled under Dr. Babasaheb Ambedkar Technological University (Lonere, Maharashtra) and its 100+ affiliated colleges.
Problem & Engineering Requirements
DBATU operates on a 10-point Choice Based Credit System (CBCS). Calculating semester grade point averages (SGPA) and overall cumulative grade point averages (CGPA) manually involves complex credit-weighted math rules, audit course exclusions, and non-linear grade point values (e.g., EX=10, AA=9, AB=8.5, BB=8, BC=7.5, CC=7, CD=6.5, DD=6, DE=5.5, EE=5, -=0).
SS Code Hub Solution & Architecture
- Exact Formula Compliance: Implements official university formulas: $\text{SGPA} = \frac{\sum (C_i \times G_i)}{\sum C_i}$ and official percentage formula $\text{Percentage} = (CGPA - 0.75) \times 10$.
- Audit Course Rule Engine: Automatically locks grade to '-' when credit is set to 0, excluding audit subjects from grade numerators and denominators.
- Android Native Responsive Experience: Designed with Material 3 segmented controls, touch-optimized minimum 44px inputs, and mobile list card transformations.
